Secure Wifi - Watchguard Test1. 2.4 GHz wavelength: longer wavelengths, better range
2. larger channel widths: provide faster speed and throughput but can
create greater interference
3.5 GHz wavelength: supports faster data rates at shorter distances,
suited for high density deployments because of greater number of
channels that do not overlap
4. What channel widths do 2.4 GHz support?: 20 and 40 MHz
5. What channel widths do 5 GHz support?: 20, 40, 80, 160 MHz
6. omnidirectional antenna: Can transmit and receive with 360-degree
coverage
7. directional antenna: directs signals where the antenna oints
8. Beamforming: technology that enables wireless devices with
omnidirectional antennas to detect location of other wireless devices
and direct a stronger signal in the direction of the devices
9. Antenna Gain: The increase in signal strength by the concentration
of radio waves by means of directional propagation.
10.ad hoc network: wireless network where stations can communicate
1/
, directly to each other
11.infrastructure network: wireless clients must connect through a
central wire- less point that controls access to the wireless and wired
networks
12.wireless network service sets: BSS, BSSID, SSID, ESS
13.mesh network: one or more AP's connected to the wired network
14.best practices for channel planning: - To avoid co-channel interference,
make sure that adjacent APs do not overlap channels.
- Larger channel widths can provide better throughput, but they can
cause more interference
in high density areas.
15.How many channels in 2.4 GHz: 14, (1, 6, and 11 do not overlap and
these are the most used channels by AP)
16.How many channels in 5 GHz: 25 that do not overlap
17.Which channels are mainly used in 5 GHz: 20 and 40 MHz
18.For high density deployments: use 20 MHz channel width in 2.4 GHz
to reuse channels
19.Co-channel interference (CCI): occurs when wireless radios transmit
on the same frequence in the same location
